Although it may be difficult to track down the source of a dripping pipe, doing so is crucial if you want to avoid costly repairs. How you go about tracing a leak depends greatly on the type of leak you're dealing with. Leaky pipes in the ceiling or walls can be difficult to locate, but the one under the sink is usually easy to spot. Assuming you've already established that a leak in one of your pipes is the issue, you'll need to go room by room to identify its origin.
While living in their home, the vast majority of people will experience some sort of plumbing leak. Frozen pipes that burst open are an obvious sign of a leak. Some, like plumbing pipes hidden beneath floors with faulty connections, are not readily apparent.
As soon as a leak is found, it can be fixed. But before you can go looking for it, you need to know how to go about finding it. In this context, we become relevant. Wagner's plumbers are experts at finding water leaks thanks to extensive training. Learn the most common water leak entry points, the best methods for detecting leaks, and why you should always call a plumber for help when dealing with a water problem in this post.
What Are The Signs Of A Water Leak?
Some leaks, depending on their source and severity, may be immediately noticeable. Most homeowners won't even be in the house when a disaster like a frozen pipe bursting through the ceiling occurs. Other leaks, however, can be much more covert. For instance, if you have a slab leak, you might not be able to tell by looking at the problem; instead, you might notice it through noticeably higher than usual water bills. Here is a list of some of the most telltale signs that you have a water leak:
- Contamination of the architectural surfaces
- Leaks in the ceiling have caused some spots there to be wet.
- Wet drywall
- Visible mould and mildew on the exterior of fixtures like showers and bathtubs
- There are cracks in the foundation of your home.
In case of a leak, you may notice a variety of less obvious signs, including the following.
- Strange, musty odours, often associated with the presence of mould or mildew.
- A significant and sudden increase in the cost of your monthly water bill.
- The sound of running water is barely audible when nobody is using it.
Verifying The Existence Of A Water Leak
If there is visible water damage in your home, it's safe to assume that you have a leak of some kind and can skip this step. You can skip this step if the water damage is obvious. However, if you detect strange odours, if your water bill suddenly spikes, or if you have a sneaking suspicion that there is a leak somewhere in your home, further diagnostic work may be necessary.
Please take this evaluation as a starting point. In the next half an hour, you must turn off all water use in your home. When everyone else is out of the house at school or work, this task is usually much less of a hassle. This includes any use of water, such as fountains or sprinklers. Do not turn off the water completely; instead, make sure that no fixtures or appliances in or around the house are using water during the testing period.
Verify the water meter's current reading. Water metres are required to have a leak indicator. Typically, this is depicted as a miniature wheel or a triangle depending on the unit. The leak metre is sensitive enough to detect the tiniest of water leaks from your home's pipes. If your water level keeps rising even after you've turned off all the water sources in your home, for instance, you probably have a leak somewhere in your plumbing.
Various Other Sources Of Leakage Inside
Indoor flooding is not limited to plumbing leaks. Although we'll focus primarily on roof leaks below, other potential causes of water damage to your home include:
Dripping Showers And Bathtubs
The shower or tub itself may develop a leak, in addition to the pipes that connect them. Water can easily drip in between floor tiles if the waterproof caulking has deteriorated over time or been removed accidentally.
If the water leak is localised to a small area around your dishwasher or washing machine, you should double-check to make sure the problem is not caused by the machine itself or one of its plumbing connections or drain spouts.
Burst Water Heaters
Tanks that have rusted over the years can develop small leaks and reduce the efficiency of older water heaters. If you've noticed water collecting near the water heater's base, this is probably the cause. The water heater's pressure-relief valve must be opened in some situations to release pressure and allow water to drain from the tank.
Plumbing Leak Detection: What You Need To Know
Authenticate The Spill
If you can, try rearranging the appliances to see if you can pinpoint when or where the dampness started. If the water supply line to your dishwasher breaks, for instance, water will leak out of the appliance and onto the floor. If this does not help you pinpoint the source of the dampness, you should turn off all water-using appliances and fixtures in your home and use a piece of tape or a pencil to mark the spot where the needle is pointing on your water metre. You should check the metre again after eight hours have passed after turning off all the faucets, appliances, and fixtures. If the needle has moved, it likely indicates a leak in the plumbing system.
Bathrooms And Kitchen
Open the drawers or doors of the cabinets beneath the sinks and use the light to check for damp spots at the seams and at the base of the P trap. Fittings and valves in the supply line that show signs of corrosion could be another sign of a hidden pipe leak. Empty the cabinet to look for telltale signs of water damage like moisture, water stains, mildew/mould, peeling material or buckled, and so on. There is a leak in the cabinet if any of these are present. Tighten up any dangling wires and wipe away any moisture. The water service must be turned back on to see if that solves the problem. When the supply is shut off and then turned back on, the leak in the valve or line is often exposed, making the problem obvious. If this is the case, the faulty supply line must be replaced. The same method can be applied to all of the water-using appliances and fixtures in your home, including the refrigerator, dishwasher and washing machine.
Ceilings, Walls And Floors
Verify the flooring in the bathroom, kitchen, laundry room, and any other area that has a water source (such as a refrigerator, dishwasher, sink). If you notice any cracks, deformations, or sponginess in the flooring, it may be a sign of moisture or a leak. In addition, the walls, ceilings, and floor of the rooms beneath the restrooms should be examined. Stains on the ceiling or walls, as well as peeling paint or bubbling, wallpaper, indicate a leak in the pipes. A plumber should be called to inspect the leak, fix it, and locate the source before any demolition work is begun.
Crawl And Basements Spaces
Pipes that are visible in the ground or in a crawl space should be checked. Corrosion or condensation on the pipe's exterior is a telltale sign of a leak. Mold, mildew, or rotting wood around these pipes are telltale signs that this is where the leak is coming from. Water stains may not always be in the same place as the leaking pipe because water naturally flows downhill. However, it is a highly accurate indicator of the general location of the moisture's origin.
Locate And Fix Secret Water Leaks
Look for and fix any tiny leaks that could eventually become big ones.
Water Wastes Through The Bathtub And Shower Splashguards
If water gets in through the cracks in your shower door or curtain, you have a splash leak. Plumbers have told us that this is the most common form of bathroom leak. Although the water seeping into the subfloor from the floor around the shower or tub may seem like a minor problem at first, it can lead to expensive repairs down the line. In a short amount of time, the vinyl flooring or tiles will start to come loose. Eventually, the plywood subfloor delamination and rots, which requires a massive and costly job to remove and replace. Here are some potential red flags:
- Peeling vinyl loose tiles or flooring near the shower.
- Near the bathroom's shower, the paint was peeling and the woodwork looked chalky.
- Stains on the joists or ceiling due to water damage.
- The appearance of mould on the floor or walls near the bathroom's water source.
- Look for standing water on the floor behind the shower curtain after you've finished using the facility.
Finding The Cause Of A Leaking Bathtub Drain:
- If your shower has a door, use it to splash water all around the outside of the door and the frame. Leaks around the frame might not become noticeable for up to five minutes.
- If your door has a rubber door sweep or rubber gaskets, make sure neither is damaged in any way by checking for holes.
- The caulk around the shower or tub's base should be checked for damage as well.
The Best Way To Stop Tub Drain Leaks:
- The proper overlap of sliding doors is essential for a proper close. Keep in mind that the door closest to the sink should be the inner door.
- To prevent water from escaping while you're in the shower, you should either instal a splash guard or make sure the shower curtain is drawn all the way.
- Water can be prevented from entering a frame by applying a thin bead of tub and caulk around its inner perimeter. Caulk needs to be applied with some force to ensure it fills any spaces between the shower's frame and surround. If there is any excess caulk, remove it right away by wiping it off. A second leak test should be performed after the caulk has dried.
- Switch out any old door sweeps or gaskets. Don't forget to bring the broken one with you when you go shopping for a replacement at a home improvement store or a plumbing supply shop (be sure to get the correct size to fit).
- If there are splits in the caulk that lines the floor, you should scrape it away and replace it with a new bead.
Leaky Bathtub And Shower Drains
If the drain has a leak, water could possibly seep in through the connection to the shower or tub. Fibreglass or plastic shower pans have a tendency to flex when you stand on them, which can break the drain seal. Sadly, this is a common problem with plastic bathtubs and shower stalls. The ceiling below could become discoloured or even destroyed by these leaks, and the floor joists could rot. Leaks from a bathtub that is installed directly on a concrete slab can cause serious damage to the flooring in the bathroom and any adjoining rooms.
Trouble In The Form Of A Leaking Bathtub Drain:
- Wet spots on the ceiling or joists.
- Floors that are either loose or wet in the area around the bathroom's bathtub.
The Cause Of A Dripping Bathtub Drain And How To Repair It.
- In cases where you can see the drain's underside through an open ceiling or an access panel, it's best to only fill the tub halfway and then let it drain. Put a towel over the shower drain before turning the water back on. Investigate the traps and drains for leaking through the bottom access panel.
- If you can't get to the drain's bottom, you should fill the area around it with water until you have a small puddle, then plug the drain (photo). Mark the wet and dry areas of the ground with a shampoo bottle. Then, you need to hold off for an hour. There is likely a drain leak if the puddle gradually evaporates. Do not rely on the bathtub stopper, as there is a chance it will leak during the test. Once the plug has been removed, a needle measuring 1.50 inches can be inserted. Connector Check (find them at home centres). Remove the grate and swap it out for a 2 in. plug.
Fixing A Leaking Bathtub Drain:
- To fix a drain in a bathtub, unscrew the flange that sits atop the drain. The flange then needs to be disinfected and sealed with silicone caulk. In addition, take the rubber gasket from under the tub's drain hole with you to the hardware store so you can purchase an exact replacement (be sure to get the correct size to fit). The drain flange should be tightened after the new gasket has been installed.
- If there is a shower drain in the basement, make sure the ring nut holding it to the floor is tightened all the way. In the event that this does not resolve the issue, the drain assembly will need to be replaced. If you can't get your hands under the drain, you can either cut a hole in the ceiling below it or swap out the entire drain assembly for a WingTite drain.
Leaky Bathtubs And Showers
Water seeps into the tile from behind when the grout or caulk behind it deteriorates. This can cause the tiles to loosen from the wall, the joists, the wall frame to rot, and, ceiling, or subfloor, below to be damaged, depending on the materials used to set the tiles. Further, this may result in the tile detaching from the wall.
Signs Of Trouble:
- Broken and loose tiles.
- Persistent mould growth.
- If the shower happens to be next to an exterior wall, there may be a patch of peeling paint there.
- A stain on the ceiling above the bathroom's shower.
Where Can I Look For The Original Material?
- Inspect the grout for cracks and the caulk for separations. Mould is an almost constant sight here.
- Check for stains or dampness by opening the access panel behind the faucet if there is loose tile behind the tub spout or the faucet.
Ways To Repair It
- Take off any loose tiles and caulk that has built up over time.
- Using tub and tile caulk, you can reattach recaulk, tiles, and regrout,if the surface beneath the tile is still stable. Tile replacement is another viable approach.
- You will need to instal new tile or backer board or a fibreglass surround if the wall is spongy and more than a few tiles are loose. Fibreglass could be used as an alternative enclosing material.
The Flange Of The Toilet Is Leaking
The area where the commode attaches to the drain pipe in the basement is prone to leaking. Every time you flush, water can seep out and damage your ceiling, subfloor, joists, and flooring.
Signs Of Trouble:
- An accumulation of water has formed at the base of the lavatory.
- Floorboards that are loose or broken.
- The ceiling below shows multiple stains.
- You can give this toilet a gentle rocking motion by pressing down on it. The wax seal between the flange of the toilet and the wall of the closet will be broken as a result of this motion.
Where Can I Look For The Original Material?
Take some measurements from the stacked walls (right photo) to see if your ceiling has any stains before you go to the trouble of removing the toilet. If the discoloration is close to the toilet, a leaking flange is likely to blame. In the event that a leak develops after the toilet has been removed (Photo 2), check for the following:
- All of the flange's surrounding floor is at or below grade.
- There are fractures in the flange.
- Broken either the bolts or the slots that the bolts fit into.
- Because it is not firmly attached to the ground, the flange can shift around as needed.
In What Way Can We Repair It?
- If you haven't encountered any of the aforementioned problems, you can give replacing the toilet with a new wax ring a shot.
- If the current flange is too short, a plastic riser can be installed above it.
- Putting in a metal repair flange is the best course of action if the flange or bolt slots become damaged.
- You should use toilet shims to level the toilet before you replace it if the floor is not flat. The toilet won't shake as much now.
Which Comes First, The Roof Or The Pipe?
For example, assume you see a moist area on your ceiling. Where do you go from here? A broken pipe or a faulty roof flashing could have resulted in this water seepage. Roofing contractors will tell you that leaks are common, and that most homeowners will have at least one leak in their roof throughout their tenure in the house. This is especially true if the roof is getting up there in age.
Leaky roofs occur when the underlayment and the roofing material (tile, shingles, etc.) both deteriorate. When this happens, the water can seep through the shingles, into the attic, and then, thanks to gravity, into the rest of your home.
How Do I Find A Leak?
You have eliminated the roof as a possible source of the leak, so now you need to look elsewhere in the house for the cause. Your home has a sophisticated plumbing system that includes pipes located inside the walls, under the floors, and even in the ceiling.
If you don't have a detailed diagram of your home's plumbing system, finding the source of a leak could require some educated guesswork. It's not as simple as it seems at first glance. Water has full three-dimensional mobility within the boundaries of your property. Water drops because of gravity. Water can go in any direction it wants once it encounters obstacles, such as insulation or studs, that stop it from draining downward.
Water damage investigation is not always as simple as removing the drywall and finding the leaking pipe. It is not unheard of, for instance, for water damage to an internal wall to originate in the upstairs bathroom.
Obtain The Services Of A Plumber
A plumber should be called in at this point to help track down the water's original point of entry. This is because a person's intuition and experience are crucial to identifying leaks correctly. Plumbers with experience like the ones we have at Wagner have seen and fixed countless water leaks in homes, so they know exactly where leaks tend to spring from and how to get to them quickly and efficiently.
Water pipe leaks, like most other plumbing problems, won't go away unless you take action. A leaking pipe won't just disappear. Water damage will only get worse if you put off fixing it until "next weekend" or some other arbitrary date. This includes the structural deterioration and mould growth that are inseparable from water damage. Leaks are an emergency that necessitates prompt action.
It may be challenging to locate the source of a leak in the walls or ceiling, but a dripping pipe under the sink is usually an easy giveaway. Due to their extensive training, the plumbers at Wagner are pros at locating sources of water loss. Find out where water tends to leak in and why you should always call a plumber for assistance. For at least 30 minutes, please refrain from using any domestic water sources. The presence of leakage damage is strong evidence that a leak exists.
Mechanical leaks and rusty water heaters are two other potential sources of water damage in your home. An ultra-sensitive water leak metre. For example, if the dishwasher's water line bursts, water will spill out onto the floor. All water-using devices should be switched off, and the location where the needle rests on the water metre should be marked with a pencil or tape. Inspect for and repair any tiny cracks that might develop into major ones.
Costly maintenance issues can develop from peeling vinyl tiles or flooring in the bathroom's shower area. The leak should be checked, fixed, and the source identified by a plumber before any demolition is started. If the bathtub is placed directly on the concrete floor, any leaks will ruin the subfloor in the bathroom and the rooms adjacent to it. The drain's flange must be cleaned and sealed with silicone caulk. There's a high potential for water damage in the basement around the toilet's connection to the drain pipe.
Tub and tile caulk is used to reattach tiles, grout, and caulk after it has been removed. Your bathroom stall wall could be made out of fibreglass instead of the typical ceramic tile. Most roofs will spring a leak at some point during a homeowner's time there. Your home's plumbing is quite advanced, with pipes hidden everywhere from the ceiling to the floor to the ceiling itself. To identify the initial entry point, a plumber should be called in.
